UI Automation Support for the Toolbar Control Type

This topic provides information about UI Automation support for the Toolbar control type. In UI Automation, a control type is a set of conditions that a control must meet in order to use the ControlTypeProperty property. The conditions include specific guidelines for UI Automation tree structure, UI Automation property values and control patterns. Toolbar controls enable end users to activate commands and tools contained within a application.

The following sections define the required UI Automation tree structure, properties, control patterns, and events for the Toolbar control type. The UI Automation requirements apply to all toolbar controls, whether Windows Presentation Foundation (WPF), Win32, or Windows Forms.

This topic contains the following sections.

  • Required UI Automation Tree Structure
  • Required UI Automation Properties
  • Required UI Automation Control Patterns
  • Required UI Automation Events

Required UI Automation Tree Structure

The following table depicts the control view and the content view of the UI Automation tree that pertains to toolbar controls and describes what can be contained in each view. For more information on the UI Automation tree, see UI Automation Tree Overview.

Control View Content View
  • Toolbar

  • Various controls (0 or more)

  • Toolbar

  • Various controls (0 or more)

A toolbar control can contain any type of control within its subtree. They most often contain buttons, combo boxes, and split buttons.

Required UI Automation Properties

The following table lists the UI Automation properties whose value or definition is especially relevant to toolbar controls. For more information on UI Automation properties, see UI Automation Properties for Clients.


UI Automation Property Value Notes

AutomationIdProperty

See notes.

The value of this property needs to be unique across all controls in an application.

BoundingRectangleProperty

See notes.

The outermost rectangle that contains the whole control.

ClickablePointProperty

See notes.

Supported if there is a bounding rectangle. If not every point within the bounding rectangle is clickable, and you perform specialized hit testing, then override and provide a clickable point.

IsKeyboardFocusableProperty

See notes.

If the control can receive keyboard focus, it must support this property.

NameProperty

Depends

The Toolbar control does not need a name unless more than one is used within an application. If more than one is present, each must have a distinguishing name (for example, Formatting or Outlining).

LabeledByProperty

Null

Toolbar controls never have a label.

ControlTypeProperty

Toolbar

This value is the same for all UI frameworks.

LocalizedControlTypeProperty

"toolbar"

Localized string corresponding to the Toolbar control type.

IsContentElementProperty

True

The Toolbar control is always content.

IsControlElementProperty

True

The Toolbar control must always be a control.

Required UI Automation Control Patterns

The following table lists the UI Automation control patterns required to be supported by toolbar controls. For more information on control patterns, see UI Automation Control Patterns Overview.

Control Pattern/Pattern Property Support/Value Notes

ExpandCollapsePattern

Depends

If the toolbar can be expanded and collapsed to show more items, then it must support this pattern.

DockPattern

Depends

If the toolbar can be docked to different parts of the screen, then it must support this pattern.

TransformPattern

Depends

If the toolbar can be resized, rotated, or moved, it must support this pattern.

Required UI Automation Events

The following table lists the UI Automation events required to be supported by all toolbar controls. For more information on events, see UI Automation Events Overview.
